Seems like four new songs, サイダー, the title track あいにいくよ produced by Hisashi Nawata (who's worked with artists such as Ryohei, Crystal K, BoA, Halcali, and Rie fu), ジェットコースター (Jet Coaster) produced by Jazzin'Park, and then an older song, called SuperLooper produced by RAM RIDER!

She performed SuperLooper back during TIME&SPACE, during a few lives. I think it's a cover, but I've never actually heard her performance myself, so we'll see!

A bonus track is being offered as well, a Takeshi Nakatsuka (produced メトロポリタン美術館 (Metropolitan Museum of Art) from TIME&SPACE)remix of Samba de Mar, a track she did for a compilation called Seaside Town.
